Figure 5. Matrixes of scatter plots of calibration data using (A) Scenario 1 and (B) Scenario 3 datasets, from Fanno Creek near Durham, Oregon. Scenario 1 data were from autosampler deployments: storm 1, June 17–18, 2002; storm 2, May 4–5, 2003; storm 3, May 8–9, 2003. Data sources for Scenario 3 include U.S. Geological Survey (USGS) historical data, Clean Water Services ambient monitoring, and autosamplers, from 2001 to 2007. All Escherichia coli (E. coli) bacteria data in (B) are from the Clean Water Services ambient monitoring program because no E. coli bacteria data were collected by USGS. Units for total suspended solids and total phosphorus are in milligrams per liter, and units for E. coli bacteria are in colonies per 100 millimeters.
